The new method reduces carbon emissions and turns wastewater treatment plants into green generators. A significant downside to wastewater treatment plants is their carbon footprint. Now, researchers have found a way to reduce carbon emissions from sewage and produce hydrogen energy at the same time. Their method uses purple bacteria and electrical currents to capitalize on the organic materials we flush down the toilet every day. We spoke with one of the study’s authors, Daniel Puyol of Spain’s King Juan Carlos University, to learn more.

Make sure to pick a microwave that supplies you a minimum of 3 power degrees. Normally, these are High, for normal food preparation (100% power); Tool, for simmering (50% power), as well as Reduced or Defrost (typically regarding 10%-30% power).

The idea of a balloon that floats high up above Earth indefinitely is a tantalizing one. Solar power would allow such stratospheric balloons to operate like low-cost satellites at the edge of space, where they could provide communication in remote or disaster-hit area, follow hurricanes, or monitor pollution at sea. One day, they could even take tourists on near-space trips to see the curvature of the planet.

The Rape-aXe is a latex sheath embedded with shafts of sharp, inward-facing barbs that would be worn by a woman in her vagina like a female condom. If an attacker were to attempt vaginal rape, his penis would enter the latex sheath and be snagged by the barbs, causing the attacker excruciating pain during withdrawal and giving the victim time to escape.

Alfredo Moser's invention is lighting up the world. In 2002, the Brazilian mechanic had a light-bulb moment and came up with a way of illuminating his house during the day without electricity - using nothing more than plastic bottles filled with water and a tiny bit of bleach.

SpaceX and Tesla Motors founder Elon Musk has often been compared to a real life version of Tony Stark, aka Iron Man. Director Jon Favreau has even openly said that Musk inspired his depiction of Stark in the first Iron Man film.

Musk has gone and created a car that is, by every indication, one of the best-built cars in the world without exception. But Musk isn’t done yet, as he presses forward with another change to the way cars are built; the elimination of side mirrors.

There are tons of gadgets to help golfers develop the perfect swing, but it’s hard to apply the same unobtrusive training tools to other sports. Evo One, though, is the counterpoint — it's a Kickstarter project that puts a tiny coach inside a basketball to help players improve their game.

In a materials science laboratory at Harvard's school of engineering and applied sciences, a transparent disk connected to a laptop fills the room with music — the transparent ionic speaker consists of a thin sheet of rubber sandwiched between two layers of a saltwater gel, and it’s as clear as glass.

Previously the idea of cleaning up the world’s oceans with their vast accumulations of disposed plastic material was considered an impossibility. Now a 19-year-old inventor says he and his foundation has a way to clean up the world’s oceans, and not only does he say we can do it, but that we can do it in five years time and produce a profit from it.

Researchers accidentally discovered the world's thinnest sheet of glass, just two atoms thick. Their chance finding — now immortalized in the 2014 edition of the Guinness Book of World Records, out this week — gives scientists a glimpse into the puzzling properties of glass, which behaves like both a solid and a liquid.

Although its effects aren’t immediate, LEGO bricks have led to more innovation by proxy than any other company. From this we understand that innovation does not happen overnight, but is the sum of a long series of sequential events.

From gunpowder to paper or ice cream, Chinese leaders like to showcase how many world-changing inventions have originated in their country. But for every huge breakthrough there are lots of quirkier ones that never made it big. A submarine that catches sea cucumbers? A funnel that helps people pee straight? A bicycle that rides on water via plastic tubes?

Like ostriches themselves, the Ostrich Pillow is enigmatic and generally fascinating. Who would use it? Is it appropriate for children? Is it a sex toy? Hard to say! But it looks downright comfortable for napping. The only issue is carrying it.

Bill Gates recently wrote the foreword for Edison and the Rise of Innovation, a new book about one of the great inventors ever. Read the foreword and view photos of some of the Edison-related items he owns.

You know what kind of sucks about riding a bike? Other than all that pedaling? Bike helmets. Sure, they keep that overrated "brain" from getting splattered, but they take a lot of the open-air-joy out of things, and they're not comfortable. A pair of Swedish women have developed a remarkable solution: the invisible bike helmet.

The Weizmann Institute’s Dorit Ron and Adi Shamir have been closely studying the movement of the semi-anonymous digital currency Bitcoin, and today published a paper that highlights an unusual set of transactions that may closely link its inventor, a mysterious figure known as Satoshi Nakamoto to Silk Road mastermind Dread Pirate Roberts.

It has been a long slog to recovery after Haiti’s earthquake almost four years ago. Thousands remain in provisional housing of plywood, tarps, and corrugated metal. New lodging is being created, though. It’s just not all of the type you might expect.

Some are available now, while others won’t come for a year or two, if ever. But all of them are ingenious in their approach to solving problems. And someday, the names of their inventors may be spoken by future schoolteachers. May we present The CNN 10: Inventions.

In Tumblr's year-in-review round up, the blogging platform collected some of the most popular posts on the site under several different categories. According to the review, Tumblr calculated popularity by factoring in "total volume of posts and tags (including reblogs) and total traffic." Tumblr users are passionate about a number of subjects, so it's no surprise the most popular tech posts highlighted some of the most innovative tech of 2013.

For over 100 years, the light bulb didn't evolve much, generally sporting the same, well, bulbous design ever since Thomas Edison gave us the original in 1879. Lately that's changed as LEDs and CFLs have challenged the conventional bulb, and now Philips is taking light bulb design in a new, flatter direction.

Stationery purveyors J.C. and Rollie Hall ran into a problem during the 1917 holiday season: Business had been too good at their Kansas City, Mo., shop, and they'd run out of the white, red, and green tissue papers that were the era's standard gift dressing.

It’s hardly news that forks and knives have been replaced with crank-fitted cutlery and laser-cutter pizza slicers. If you even try to stab your salad with an ordinary utensil, you risk being shamed by your contemporary diners. For those tech-savvy ladies and gents reverse-chilling their beer and popping out Twinkies in waffle makers, this one’s for you.

Designer Jeabyun Yeon has created something great. Essentially it turns humans into fish. 'Triton uses a new technology of artificial gill model.- It extracts oxygen under water through a filter in the form of fine threads with holes smaller...
